Cosmetic microneedling, also known as collagen induction therapy, is a minimally invasive cosmetic procedure that involves using fine needles to create controlled micro-injuries to the skin. The procedure stimulates the body’s natural healing response, which leads to the production of collagen and elastin, two proteins that are responsible for the skin’s firmness and elasticity (1).
Microneedling is similar to, but not the same as using a derma roller. While both aggravate the skin, derma rollers are often used at home. while microneedling is often done by an aesthetician.
How is Microneedling Done
The procedure is typically performed using a device known as a microneedling pen (2), which has a small barrel that is covered with fine needles. The needles penetrate the skin at a depth of 0.5-2.5mm, depending on the desired outcome and the area of the skin being treated. The procedure is relatively quick, with most treatments taking 30-45 minutes to complete.
Microneedling is commonly used to treat a variety of skin concerns, including fine lines and wrinkles, acne scarring, hyperpigmentation, and uneven skin tone. It can also be used to improve the overall texture and tone of the skin, and to enhance the penetration of topical skincare products. (3)

Benefits of Microneedling / Derma Rolling
One of the main benefits of cosmetic microneedling is that it is a relatively safe and well-tolerated procedure (4). There is minimal downtime associated with the treatment, and most patients experience only mild redness and swelling, which typically subsides within a few hours to a day.(5)
The procedure is typically performed in a series of 3-6 sessions, spaced 4-6 weeks apart. The number of sessions required will depend on the individual’s skin condition and the desired outcome. Some patients may notice an improvement in their skin after just one treatment, while others may require multiple sessions to achieve their desired result.
The results of cosmetic microneedling can be quite impressive. Patients often report a significant improvement in their skin’s texture and tone, as well as a reduction in fine lines and wrinkles. Acne scarring and hyperpigmentation can also be significantly improved with the procedure.

Disadvantages of Microneedling
There are some potential risks and side effects associated with cosmetic microneedling and derm rolling. These may include redness, swelling, and itching. In rare cases, the procedure may cause scarring or infection. Patients with active acne or rosacea should also use caution when considering the procedure, as it may exacerbate these conditions.
There are a few potential disadvantages of cosmetic microneedling and using a derma rollerto consider. These may include:
- Pain and discomfort: Some patients may experience mild pain or discomfort during the procedure. A numbing cream can be applied prior to the treatment to minimize this.
- Risk of infection: There is a small risk of infection associated with cosmetic microneedling, particularly if the needles are not properly sterilized. To minimize this risk, it is important to choose a reputable practitioner who follows proper infection control protocols.
- Risk of scarring: In rare cases, the procedure may cause scarring, particularly if the needles penetrate the skin too deeply or if the patient has a history of keloid scarring.
- Risk of hyperpigmentation: Patients with darker skin tones may be at increased risk of hyperpigmentation (darkening of the skin) following the procedure. This is more likely to occur if the needles penetrate the skin too deeply.
- Downtime: Although microneedling is a minimally invasive procedure, patients may experience some redness and swelling following the treatment, which can last for several hours to a day.
- Cost: The cost of microneedling treatment can vary widely depending on the location, the practitioner, and the number of sessions required to achieve the desired results. It can be an expensive procedure.
- Not suitable for everyone: Patients with active acne or rosacea should use caution when considering the procedure, as it may exacerbate these conditions. Pregnant or breastfeeding women should also avoid the procedure.
Cosmetic microneedling is a safe and effective procedure for improving the appearance of the skin. It can be used to treat a variety of skin concerns, including fine lines and wrinkles, acne scarring, hyperpigmentation, and uneven skin tone. The procedure is relatively quick and well-tolerated, and most patients experience only mild redness and swelling. The results of the procedure can be quite impressive, with many patients reporting a significant improvement in their skin’s texture and tone.
